Application December 23, 1939,Serial NO. 310,812 1f claim.- (c1. sz-89) This invention relates tobottle coolers and has r its object to provide a new and improved de-`cooler wherein bottleswith beverage therein may be eillciently kept in-a` cooled condition without In the bottle coolers as now used, thebottles are water or a fan or mechanical air moving device of some kindis used to circulate the air in the cooler. l One of the objects of thepresent invention is to provide a dry bottle cooler which workseffectively without any mechanical air moving device, such as a fan.`The invention has asa further object to provide-a bottle cooler whichmay be used either dry or with water in which the bottles are placed.further objects which are more particularly pointed out in theaccompanying description.

Referring now to the drawings,

Like numerals refer to like parts throughout the several eures.

Referring now to the drawings, I have shown one form of bottle coolingdevice embodying the invention. In this construction there is a heatinsulated receptacle, which consists of al bottom and upstanding sidesand ends, in which .the bottles are received. The interior of the bottlecooler is preferably made of a metal receptacle i The exterior surfaceis preferably made from a metal receptacle 2 and the space between thetwo metal receptacles is lled with heat insulating material 3.

Within the receptacle i there are preferably provided two refrigeratingmembers or evaporators d and 5 of any desired construction, butpreferably of a thin plate construction, suspended in substantiallyparallel vertical planes, that is evaporators which ,are comparativelythin and made up of separated metal walls with means for showing thecon- 'I'he invention has` Fig; 3 is a plan view of Fig. 1 with the coverre- I this descriptionfor use in cooling bottles water 'or other E rator4 and its .associated wall.

these evaporators are above the. bottom of the the walls. Theseevaporators preferably have smooth or they may be made of the type assetout in my where the refrigerant when circulated back and forthv between4the walls of the plates, makes direct contact with .the these wallsform primary cooling surfaces.

These evaporators are suspended by any supporting means, so that thereis a free space 6 between the evaporator 5 and its associated wall and afree space 1 between the' evaporeceptacle I so as to provide spaces 8and 9 between the bottoms of the evaporators'and the 4 bottom of lthecooler upon which the bottles to parallel to the evaporators.

closing. This is. particularly desirable whenv circulating a refrigerantback and forth between w be cooled rest. As herein shown the evaporatorsare supported by means of the brackets 4a and 5a which are connected tothe evaporators and to the wall of the cooler.

Between the` evaporators space I0 in which the bottles ll to be cooledare located. The bottles are preferably stood up on their bottomsbetween the evaporators so as to be in a substantially vertical positionsubstantially The cooler is provided with a top of any suitable kind. Iprefer to form the top of two doors I2 and i3 pivoted or hinged at I4 sothateither can be moved alone. I also prefer to provide some means forpreventing the doors from completely warm bottles are placed 1in thecooler. This result maybe secured in any desired manner, as by providingstops l5 and I6 against which the doors The evaporators may be connectedto any source of refrigerant supply. I prefer, however, to provide arefrigerating apparatus arranged to form 'a part of the device and whichis located in a receiving space I9 underneath the bottom of thereceptacle l, at one end of the device. This space walls of the'platessovthat.

The bottoms'A of is an open topped the pipes 25 and 26, with anexpansion valve 21,

'in any oi theusual ways.

When the device is in operation and the refrigerant circulating throughthe evaporators, the air on both sides of the evaporators is cooled anddrops down. It will be noted that by this l construction both sides ofboth evaporators are in the bottom of space 9 t6 the central space I0containing the Y bottles. 1 between the evaporator Wall is cooled anddrops down and passes under the evaporator through space 8 into thecentral space `I0 where. the bottles are received. 'I'he air next totheopposed faces of the evaporators is also cooled and drops where thebottles are received, so that both sides of each evaporator are used forcooling the central space I0 containing the bottles.

Some means is provided for automatically shutting down the motor whenthe temperature in the cooler reaches a predetermined point. 'As hereinshown, there is provided a bulb 28 located between the two plates orevaporators 4 and 5. This bulb is connected to the chamber 29 providedwith a diaphragm 30 having an electrical contactA 3 l therewith, towhich is. connected a conductor 32 which connects with the motor 23.There-is an electricalcontact 33 opposite the diaphragm, which isconnected by a conductor 34 with one of the conductors 35 of the In thesame way the airin the space 4 and its associated source ofelectricsupply. The other conductor 36 of the source of electric'supply isconnected by conductor 31 with the motor. When the temperature risesabove a predetermined point, the diaphragm is moved to connect thecontacts 3| and 33 so as to connect the motor 23'in circuit and cause itto operate the refrigerating apparatus. When the temperature falls belowva predetermined point, the diaphragm 30 is moved so that contacts thecircuit through the motor broken and the motor stopped. The size of theevaporators with relation to the size of the 'container and the lead ofbottles in the container is such that the evaporators are defrosted, yetthe desired temperature is maintained throughout the cycle, this desiredtemperature being the temperature the user wants, a preferabletemperature being a temperature of about 38 degrees Fahrenheit.

down into the space I3 3| and 33 are disconnected and 'Ihe usual type ofbulb 33 to controly the expansion valve 21 is provided. As shown, it issecured to the return lpipe to the compressor near the evaporator 5. Anylaccumulation of water resulting from defrosting may be drained byremoving the plug 39 from the aperture 40 the receptacle i. Guard stripsII- are placed at each end ot the receptacle, near the top, to protectthe pipes and bulb from injury when bottles are being loaded orunloaded.

In using the devicefthe bottles are placed in the space I0 between theevaporators I and i and the refrigerant circulated through theevaporators so as to cool them, the cool air from both sides of bothevaporators dropping down and being discharged intothe space I0 betweenthe evaporators, cold air thus surrounding the bottles and cooling them,the warm air passing up to the top of the bottle cooler. By means ofthis device the bottles can be quickly and effectively air cooled to anydesired temperature without the use of water and without the use of anymechanica1 air moving device, as the evaporators by their locationinsure a proper circulation of the cold air around the bottles bythermosyphonic action, so as to provide a substantially uniformly cooledbottle receiving space between the evaporators.

I claim: A. bottle cooler comprising a heat insulated receptacle havinga top and two separated evaporators having continuous imperforate sidewalls suspended in substantially vertical planes with a bottle receivingspace between them open at the top, said evaporators spaced apart fromthe side walls and the bottom of the' receptacle, so as to provide anair space between each of the evaporators and its associated side wailclosed at the sides and open at the top and bottom and between thebottoms of the evaporators and the bottom of the receptacle, the airbetween the evaporators and their associated side walls being cooled andbrought into the bottle receiving space by thermosyphonic action, thebottles being inserted and removed through the open top ofthe bottlereceiving space between the evaporators, a door for said open top andmeans for holding said door partially open so that warm air may escapewhile it is being cooled.
